Fig. 24 lis a detail,

the apparatus for sinkingwells by means of rotary and reciprocatingdrills, which may be used separately or together in connection with aWater-supply, and to improve the tnbing, and means for closing it whenthe well is complete. I accomplish these objects by .improving theconstruction and operation of i the dierent parts and the entireapparatusv as a whole, as illustrated in the drawings, and hereinafterspecied.

That which I claim as new willfbe pointed out in the claims.

In the drawings, A represents a well-tubing formed, as usual, ofsections coupled togetherf by couplings a, and, as shown in Fig. 2,provided with a coupling a, having a side nozzle near its upper end forthe discharge of water. This tubing A is to be of any desired diameter.

B is the lower end section or filter lof the 7o tubing, which hasperforations b, for the entrance of water, and ribs d on itscircumference.

C is a rotary drill or cutter head, which is provided with cutting-teethc on its lower edge, as usual, and at its upper end is screwed onto thefilter B. This drill has a taper or shoulder cf on `its interior loweredge, as shown in Figs. l and 3.

D is a wire-cloth or perforated screen se- 8o cured to the section Bbetween the ribs d. The ribs dare a protection for the wire-'cloth frominjury when the tubing is rotated while the well is being sunk. Thiswire-cloth D and the perforatedeud or section B form a `l lter for thetube when completed.

E are the blades of an expansion-drill, eac?` having cutting-edges e.,as shown iii-Figs. 1=, 5, 6, '7, 8, and 24.'

. F (see Figs. 9 and 10) is a socket havinga 9o slot F part-way of itslength to receive thef. drill-blades E, which are pivoted in the lowerend ofthe slot F by a pivot f". As shown in Fig. 9, the socket F has ashoulder or taper` 'l f on its exterior lower edge corresponding withthe taper or shoulder c of the drill-head C, which furnishes a means ot'support for the expanding drill from the tubing A. G is the expandingpiston which fits within the socket F and at its lower end isprovidedroo with wings g, which fit in the slot F, as shown in Figs. 6 and 7.This expanding piston has openings g for t-he passage ot water, as shownin Fig. 11, and a central stem G, as shown in Fig. 5, G, and 7.

lll is a cap or collar loosely mounted on the stem G of the expandingpiston G and adapted to tit in a recess h in the socket F, and held upin the recess by a spring 7L, which rests on the top of the piston-headG.

l is a head or casing in which the socket 1J1 is located. 'l`his.casingis screwed onto the socket F, and the socket F is coupled to thedrill-rod by a coupling i, which is screwthreaded so as to screw on inthe reverse direction from the rotation intended for the drill.

l is the drill-tube for the expansion-drill.

K is a packing formed of two plates j j, and a suitable packing jbetween the plates j. This packing is secured on the drill-tube J by asuitable coupling k, as shown in Fig. l.

lL is a conical plug, which fills the lower end of the drill-head C,fitting the taper or shoulder c. After the well has been sunk the plugis dropped into the tubing to close the bottom of the tubing, so thatthe water must enter through the perforated end or iilt-er E.

M (see Figs. l2 and 25) is a watersupply head having supply-hose Nattached thereto by couplings m, and secured tothe drill-tube d by astufiingbox n.

0 is a swivel secured to the supply-head M.

P is a pulley-block connected with the swivel 0 by a link o.

Q is a hoisting-rope. This rope Q may run through an upper pulley-blockit and the lower block P, as shown in Fig. Q5, or it may be attacheddirectly to the swivel@ by a link o, as shown in Fig. l2.

S are clamping-bars to clasp the drill-rod J, each oar having a bend pto fit against. the rod, and the bars S are clamped tothe rod by bolts qpassing through them.

'li are clamping-bars for attachment to the tubing A and to theclamping-bars S. llach bar at its center is formed with a bend r to titthe tube A, and at its outer end with an arm s, having at the upper enda hook t to tit over the ends of the clamping-bars S. The clamping-bars'l are secured together and clamped onto the tubing A by suitable boltsu. These clampingbars S and T form a connection between the tubing A andthe drill-tube .Lby which the drill-tubeJ can be rotated from therotation ofthe tubingA or the tubing can be rotated from the rotation ofthe drill-tube J, and in ease it is desired not to havethe commonrotation by looseningeitherthe @lampi iig-bolts q or u the connectionbetween the tubing A and the rod J is broken, and either one can berotated without rotating the other.

diie tubing A and the rotary cutter C are sunk by rotation in theordinary manner untii the 'friction on the side ot' the hole preventsfurther rotation and descentby force of gravity, or the cutter C ceasesto act. When this point is reached, an expansion-drill and its tube J isinserted in the tubing Ato work with the tubing or independent thereof,as maybe necessary. When the expansion-drill is used, it is of adiameter to tit the cutterhead C. Such expansion-drill can be workedeither by raising and dropping or by rotation, as desired. Theexpansion-drill and rotary cutter herein are designed to work togetheror separately. \Vl1en the expanding drill is used to sink the hole belowthe tubing, the head must be smaller than the end of the cutter C inorder to pass through it.

rlhe parts of the expansion-drill are assembled by placing the spring hon the stem G of the expanding piston G and the cap Il on the stein Gabove the spring, and then inserting the expanding piston G in theblade-carrier F, with the wings g in the slot F" and the cap ll intherecess h. The blades are then inserted in the calrier l" and secured bythe pivot-pin f.

The casing I is screwed onto the carrier "F from the upper end until itcomes iu Contact with the shoulder f, as shown in Figs. 5, 6, and 7, orit is screwed onto the carrier F from the lower end, as shown in Fig.24, in which case the shoulder or bevel f is on the casing The easingthus forms a covering for the blades and carrier and also prevents thewithdrawal of the pivot-piaf".

'.lhe expanding drill is used by inserting the head i, with the partsconnected thereto, and the drill-tube J, into the tubing A until theshoulder f at the lower end ot the carrier E, or a suitable taper at thelower end or" the head i, as shown in Fig. i, rests upon the shoulder oriiange c" ot' the drill-head C, and when in place the tubing A and thedrill-tube J can be rotated together by connect-ing them one with theother through the clamping-bars S and 'l`,or they can be rotatedindependently, or the drill-tube J can be reciprocatcd, or both tubingand tube can be reciprocated.

The drill-blades are expanded by the expanding piston G, which pressesupon the corners of the blades, as shown in Figs. (i and 7. Theexpanding piston G is pressed down by the force of the water inthetubeJ, which forces down the cap il and the pist-on G through the springh", which forces the blades open. The water passes down around the cap1I and through the holes g in the expanding piston @,oraround the edgeso said piston to the point of cutting. 'ihe water thus used washes awaythe cuttings of the drill, keepingthe drilthole clear.

water-pressure in the tube J. When the water-supply is cut offfthespring h will litt the cap il into the recess fz, and the nistonG willrise, relieving the pressure on the blades and allowing the drill-bladesE to be eiosed. By this means the expansion of the blades l iscontrolled by the water-supply.

"When the rotarycuttert has become worn w rllie blades y, it will remainexpanded as long as there is a iOC , expands the blades E below thedrill-teeth c,

when the tubingA and tubeJ can be rotated or reciprocated together, asnecessary for the L work to be done, or the tube and expansion- .is inplace, thus obviating the necessity of are applied, as shown in Fig. 12.

drill can be operated alone. The shoulder or bevel c" is also designedto form a contactface for the plug L, which is driven into the tubing toclose the lower end when the well Yis complete, thus permitting thewater to enter .through thelter B only. The wire D of the lilter isprotected during the descent of the tubing A by theribs d on the ilterB.

In using the expanding drill no removal of the tubing of the well isnecessary, and when the well is cm plete the tubing, with its vfilter,

pulling up the tubing, which would allow the walls of the well to cavein.

In order to rotate the drill-tube J and tubing A together, theclamping-bars S and T are used. When it is desired to rotate thedrilltube J from the tubing A, the bars S and T Then it is desiredtorot-ate the tube J, the clamp is applied, as shown in Fig. 23.W'heuever it is desired to rotate either the tubingA or tube J alone,the clamping-bars S and'l are loosened or removed. `By means of thehookst on the bars T, which hook over the bar S, and the shoulder fofthe carrier F of the expansiondrill, which rests on the shoulder c" ofthe rotary cutter' C, thetubing A and the tube J are locked together, sothat they can be reciprocated together by the rope Q.

The water-supply head M is attached to the tube J, which supplies thewater for washing away the cuttings at the point of cutting and alsoopens the expansion-drill. .The packing K prevents the water frompassing up through the tubing and forces it to pass up outside of thetubing. XVhen it is desired to give a sudden force or impetus to thewater, the tube J is raised in the tubing A and dropped, which causesthe packing K to force the water below it out below the cutter C,thereby Vremoving any clogging at that point.

In order to rotate both `tube J and tubing -A together or separately,and to reciprocate them together or separately, and to raise eitheralone or both together, I provide the following' combined. 'clampingdev-icc and winding-drum:

A' represents theside pieces of the frame. B' are cross-piecesforsupporting the bottom plate of the clamp. n

C' are cross-pieces for supporting the drm-1 G is a plate having on itsunderside leaves or cogs b', to mesh with the leaves a.' of the 4wheelF'.

H' is the bottom plate, bolted or otherwise secured to cross-piece B',and having an annular Iiange d', which lies outside of the flange c' ofthe plate G' ,which iianges c" and d' furnisha bearing and support forthe plate G.

I' are uprights, secured to the plate G' by bolts e on opposite sides ofthe central opening ot the plate and in line, as shown in Fig. 13. i

J are clamping-bars, each bar at its outer end having a hookf to passaround the uprights I', and each bar having at its center an angularbend g' to bite against the tubing A. The bars J are attached to eachother by bolts h' and hand-nuts i', by means of which the two bars J canbe drawn together to cause the angular bends g to firmly bite thetubing. By using two bars J', each having an angular bend g', the centerof the tube clamped willalways bein the line between the hooks f', sothat tubes of different diameters can be clamped and not interfere withv the engagement of the hooks f with the two uprights I.

.As shown, two sets of clamping-bars J are used.` One set is attachednear the lower ends of the uprights I and the other near their tops. Asthe tubing descends and the bars reach their limit of descent, they areloosened and raised alternately. By this means the tube will becontinually rotated.

K are journal-boxes on the side pieces A.

o' is a lever for operating the brake-band m. The levero is hinged to abracket q on the frame S", and connected to the band m' by a link p.

U is a gear-wheel loosely mounted on the IOO IIO

driving-shaft R. This wheel U has a hub U, in which is a cam-groove uand a faeceam u'.

"V is ahead or block, which is keyed onto the shaft R by set-screws iand is provided with a sliding latch V'. The latch Vis pro.- vided witha pin 1f in its outer end, which runs in the cam-groeven. This pinar ispreterable to the forgings on the latch heretofore used, because whenworn it can be readily and cheaply renewed. The inner end of the latch Vruns in a groove 7" in the end of the drum '1" and engages with acateh'or block s', secured in the drum T. rlhe block or head Visprovided with cushions v', made ot' rubber or other yielding material,as shown in Figs. 19 and 21, to relieve the shock of the engagement ofthe latch V with the catch s.

X is a worm-gear to engage with the wheel U, mounted in a frame X',which is hinged to the frarue S. The Worm-gear X has a hand-wheel a", bywhich it can be rotated. As shown in Fig. l5, the worm-gear X can beturned up out of engagement with the wheel U.

The lever W has a beveled shoulder x to engage with the hand-wheel .frfor lifting the worm-gear X out of engagement with the wheel U when thelatch V is thrown out of engagement with the winding-drum.

Y is a ratchet-wheel loosely mounted on the shaft R. flhis wheel has aclutch y on its interior face to engage with a clutch y' on the end ofthe winding-drum T. This Wheel Y is moved longitudinally on the shaft Rby a lever-Y', which is pivoted to a bracket Y" on the frame S, and hasa collar y", which enn circles the hub of the wheel Y.

Z is a worm-gear to engage with the wheel Y, said gear being mounted ina frame Z', which is hinged to the frame S. The wormgear Z has ahand-wheel E, by which it can be rotated.

Z is a hooked link for connecting the levers y' and worin-gear Z.

.2" is a shoulder on the lever Y for lifting the hand-wheel z.

`When the lever Y is moved to throw lthe clutch on the wheel Y out ofengagement with the Winding-drum, the worm-gear Z is at the same timethrown out ot' engagement with the Wheel Y.

The operation of the rotating and reciprocating device is as follows:The power-shaft R', which is driven by steam or horse power, drives theshaft E through the sprooketwheel Q', chain P', Wheel 0', shaft L', andbevel-Wheels M. rlhe shaft E rotates the plate G' through the beveledgear F'. The `tubing A, as shoven in Figs. 13 and 14, or tube J, asshown in Fig. 23, is inserted through the opening in the center of theplate G', and is` clamped by the clamping-bars J' on the uprights l.rihe bars J are drawn together by Quaero the bolts h' and handlnuts z"or other suitable meansto cause the angularbendsg' to biteonto the tubeor tubing. The rotation of the plate G', carrying the uprights ll',rotates the tube or tubing through the clamping-bars Jl. The descent ofthe drill carries the clamping-bars J downward on the uprights ll',because they are simply hooked onto the uprights l'. As theclamping-bars reach their limit of descent, they are loosened and raisedalternately without stopping the machinery. tVhenever it is desired tostop the rotation of the tube or tubing, the clamping bars J areloosened by unscrewing the hand-nuts i', or if it is desired to stop theentire rotating device the clutch M is thrown out of gear by the leverN. By the use of the bars S and T, already described, the tube andtubing are rotated togetheru This rotary clamping device is very simpleand effective and can be used in connection with the winding-drum forreciprocating device, because it is so easily thrown out of or int-ouse, and also because it permits a longitudinal movement in the tube ortubing.

'lhe operation of the Windingdrum is as follows: Thev rotation of thepower-shaft R rotates the head or block V, and the latch V engages withthe catch s' on the Winding drum, winding the rope Q onto the drum andlifting the drill-tube. cam-groove u until the cam u draws the latch Vaway from the catch s', releasing the vrinding-drum, which is rotated iuthe reverse direction bythe weight of the drill-tube on the rope Q. Whenthe pin t' passes the releasing point in the cam-groove u, it isimmediately returned by the cam-groove u, forcing the latch Y' againinto the groove r to engage again with the catch s'. As the eamgroove ureturns the latch quickly, ll provide the face-cam u to engage with theend of the latch V' and assist the cani-groove u in returning the latch.'lhe face-cam u' being farther from the center of rotation than theca1n-groove u, it moves more rapidly and will accordingly move the latchY' linto engagement with the winding-drum catch with a quick positivemovement. By continuously rotating the head or block Y it is evidentthat the drum will be alternately Wound forward and allowed to beunwound, alternately lifting and dropping the drill tubing or tube. Byrotating the Wheel U forward or backward by the worm-gear X the positionof the cam u is changed, so as to release the latch later or sooner, asmay be necessary, thereby regulating the drop of the drill as needed.The rope Q can be continuously Wound onto the drum for raising thedrill-tube by raising the Worm-gear X out of engagement with thegear-WheelU, allowing the Wheel U to rotate with the head V, as shown inFig. l5. When it is desired to throw the latch V' out ot engagement withthe catch s' of the Winding-drum, so that the drum can be heldstationary or unvvound, the lever W 1s moved to the right, moving thewheel U l'lhe pin v runs in the l IIC' 'cam, which gives the latch a 1inmy present device.

and head V to the left, withdrawing the latch Y from engagement with thecatch s', and lifting the worm-gear X by the engagement of the shoulderwith the hand-wheel a', thereby permitting the head or block V and WheelU to rotate with the t shaft without engaging with the drum T. The latchV is rectangular inl cross-section and the pin c projects on each sideof the latch V', so that when the pin v or the end of the latch V' be--comes worn the latch can be Itaken 'out and turned over, presentinga newface for engagement with the catch s', and a new pin c to run in the camu. The drum is held against backward rotation by the pawl j and ratchetlwhen it is desired to hold the drum stationary. When it is desired toallow the-weight on the rope Q to descend, the pawlj is lifted and therotation of the drum is controlled by the brake fm', as usual. Then itis desired to hold the drum stationary or turn it slowly forward orbackward in raising weights, the clutch y on the wheel Y is thrown intoengagement With the clutch y on the drum T and the worin-gear Z is heldfirmly in contact with the wheel-Y, preventing the rotation of the drumT and wheel Y. When desired, the worm-gear Z can be rotated by thehand-wheel Z, turning the drum forward or backward, as desired, thusoperatin g the drum independently of the power shaft R. The link fr ofthe lever W and the link y" of the lever Y are designed to hold theworin-gears to which they are respectively applied in engagement withtheir gear-wheels. These links are preferably made detachable from theworm-gears, so that the worin-gears can be lifted independently of thelevers WV or Y; but it is evident that they may be made so as to liftthe worm-gears without the use of the shoulders on the levers lV and Y.

As shown in Fig. 22, the wheel Y has ratchet teeth or cogs to hold morefirmly against the worin-gear and to permit the drum T to rotate forwardwith the shaft R' when the worm is in engagement, permitting the rope tobe `wound on the drum, while preventing unwinding and avoiding injury tothe cogs when the drum T is rotated from the opposite end.

In my former patents, No. 258,889, dated June G, 1882; No. 871,548,dated October 18, 1887, and No. 382,689, dated Mayl, 1888, are showndevices for a similar purpose; but the latches there shown are throwninto engagement with the drum by springs instead of by a positive.motion It isy evident that the form of the cam on the wheel U may bevaried, as is necessary for the form of latch used, the present form ofcam and latch being best now known to me.

By means of the clam ping-bars S and 'l and the shoulders f and c thetubing A and tube J are locked together, so as to be rotated together,and by meansof the hydraulic expansion-drill the drill-blades areexpanded by the water while the weight of the rod `J is supported on thetubingA. By means ot the rotary clamp and the winding-drum the tubing Aand ltube J can be rotated or reciprocated simultaneously or separatelyand the motion of the tube or tubing can be changed from rotation toreciprocation, or vice versa,without stopping the machinery. The tubecan also be lifted without stopping the power or held stationary orlowered slowly or quickly, as may be necessary.

The dierent parts are all operated and controlled in such manner vthatone operator can easily control the working of the drill."

The feed of the drum is controlled by the worm-gear X, so that as thedrill descends the rope can be gradually let out by the operator byturning the hand-wheel .r.
